1 case question available
Thrombosis of bilateral transverse dural sinuses was noted, especially on the right side. Anecdotally, the right transverse dural sinus is dominant in 80-90% of adult patients.
The presence of an occipital sinus decreases with age.1 In this patient, a prominent occipital sinus was noted on the right side. The occipital sinus provided collateral drainage for cerebral venous flow to the internal jugular vein. Due to a lack of any complications (i.e. hemorrhage, hydrocephalus), patient deferred any interventional endovascular treatment such as thrombectomy or a TPA thrombolysis.
